whereby the said bolts may besimultaneously projected. orwithdrawn bythe manipulation- With the foregoing and other objects in view, whichwill appear as the description proceeds, this invention consists in thedesign and construction of my attachment or device whereby the objectscontemplated are at tainod, as hereinafter more fully set forth, pointedout in the appended claims, and illustrated in the accompanyingdrawings, which form apart of this application, and in which:

Figure l, is a view in elevation of a bank vault with the vault doortherefor in open position, showing oneembodiment of my invention inoperative position on said door;

Figure 2, is a view i section taken on line 2--2 of Figure 15' Figure 3,is a view in perspective of my attachment or device embodying myinvention; and

Figure 1, is a modification thereof, shown in perspective.

In order that my invention may be more fully understood, I haveillustrated in the accompanying drawings, which are referred to hereinand form a part hereof, one embodiment of the invention as applied to abank vault door, the same serving to illustrate by way of example theprinciples of the invention.

Referring to the specific embodiment of the invention illustrated by Wayof example in the drawings, the reference character 1, represents avault of well known construction' of the kind generally used in banks orthe like, the said vault having a rectangular opening therein in whichis fitted a door frame 2, to which is hinged by means of hinges 3, avault door 4, of a well known construction. The vault door 4, may be ofany desired thickness, and is of course, adapted to fit snugly in thedoor frame 2, to close the opening therein.

In the usual construction of vault doors of this character, the door isprovided on. the inner face thereof with'a system of bolts which areoperable to slide out of and into the edges of the door, to engage anddisengage the door-jamb, in locking and unlocking the door. In thespecific type of door illustrated in the drawings, the door is providedwith a bolt frame 5, on the inner face thereof, and interior ribs 6,through which a series of bolts pass in sliding out of and into theedges of the door. In the type of door shown there are provided twosystems of bolts 7 and 7, horizontallydisposed, one on each side of thedoor, and two systems of bolts 8, and 8, vertically disposed, one ateach end The bolts 7, and 7, are conof'a single operating mechanism,provided therefor on the door. Th1s operating mechanism is shown at 11,and is of a well known construction, and is connected by means of a rod12 w1th the bar 9, for moving the same relative to the edge of the door.Any movebolts, by means of a pair of bell crank levers 13, which arepivoted on the door, and have one of their ends connected toone bolt 1nthe system 7, and the other one of their ends connected to a bolt ineach of the other systems.

Thus it will be understood that by manipulating the operating means 11,a simulta-. neous projection or withdrawal of the bolts is effected. Theconstruction above described forms no part of the present invention andneed not therefore be described more in detail. Obviously, when the dooris in open position, the bolts may be either withdrawn or projected. v

In connection with a vault door of the character above described Iprovide an attachment or device adapted when placed in operativeposition on the door to prevent the closing of the same. The devicewhich I provide may comprise an open sleeve, or the like, generallydesignated by the reference character 20, and of the shape shown in Fig.3, of the drawings. The shape and size of the sleeve 20, is such as tobe adapted to be readily sprung over a portion of a bolt, and to be heldthereon bythe resiliency of the metal of the body of the sleeve. Eitherone or both of the edges adjacent the opening in the sleeve 20, may beshaped to form a lip 21, for

ice

facilitating in positioning the sleeve on the bolt. The sleeve is madeof such a material and is so finished and fitted on the bolt as not tobe noticeable thereon or distinguishable from the rest of the bolt whenit is placed 7 in operative position thereon. The length of the sleeveis such as to permit it to be placed or sprung over a portion of thebolt when the latter is in pro ected position, the said sleeve beingreceived and held between a portion fixed on the door, such as one ofthe ribs 6,

for example, and-a portion fixed. oifrigidly secured on the bolt, suchas the plate or bar 9, for example. In Figure 1, is shown two suchsleeves in operative position on the door, one

llU

is positioned on a bolt in thesystem 7, and is held between the bar 9and the adjacent rib 6, and the other is positioned on a bolt in thesystem 7 f and is held between the bar 9,

and its adjacent rib 6.

' It will be readily understood that when the sleeve or sleeves 20, areplaced on the bolts on the door, it willbe impossible to withdrawthebolts without first removing the said sleeves. Since these sleevesare made to simulate the portion of the bolt adjacent thereto so as notto be noticeable thereon, one

not knowing that the sleeves are on the bolts,

'' avoided.

will be unable to close or look the door, as the same cannotbe closedwithout first removing the sleeves; Thusit will be noted that theunauthorized removal. of the sleeves by one not aware of their presencewill be In practice, when the bank vault is opened at the beginning oibusiness, the bolts are moved to their pro ected position and one ormore of the sleeves placed in operative position on one or more of thebolts, the numberv o l sleeves employed depending upon the desire oftheoperator. The sleeves are left on the bolts until it is desired to closethe vault door at the close of business, at which time they mayberemoved, but they may be re moved only by a person authorized to doso, as no one else will known of the presence or location of thesleeves.

In the modifieation shown in Figure l, the sleeve may be provided at thelower portion thereof, where it will be concealed from View wheninposition on a bolt,with' a'rib or pro jection22, which may be stampedout'of the body oil the sleeve, or formedin some other suitable manner.This projection or rib is provided for the purpose of facilitating theremoval of the sleeve, as it provides a means by which thesleeve may begrasped, and moved away from the bolt.

It will thus be noted, that a person not aware of the presence of thesleeves on the bolts, nor of the location of these sleeves will beunable to close the door, as the same can not be closed without firstremoving these sleeves.

The ob ects ot the invention are accomplished in a very simple mannerbythe construction shownand described, but it is considered that thesame; is capable of many alternatives without departing from the spiritof the invention as defined in the ap-'- pended claims.

it will be noted that the invention is capable or use on any door'providedwith a system of bolts or the like, and which bolts ,ii'iay bereached from the inner face of the.

door.
